My invention relates'to and has for a pur-;

pose the provision of a lighting fix 'tu re particularly adapted although not necessarily,

for outdoor lighting systems alnd embodying 1 the desirable qualities of simplicity,"fdurabil ity, weather-proofness, and inexpensiveness provide a lightingfixtureembodying a re fiector composed" of an; outer' section and an inner socket supporting section detachably associated with the outer section and" co -acting therewith to form a compartment into which feed wires are readily introduced and connected to the socket witli' the utmostjease when the sectionsare disassembled, allwhile permitting the section's tobe readily assembled when "the necessary wire connections have been made so that "the'ih stallation of the:

fixture is greatly facilitated; L e V I I will describeon y three forms of lighting fixture embodying inventionfand will then point out the, novel features thereof in claims. v i

In the accompanying drawing: Figure 1 is a view showing :plan', one form of lighting fixtureembodyin'g-myinvention.- Figure 2 is 'a' vertical" sectional view taken on the line 2'2 ofFigu're 1; Figure 3' is a fragmentary vertical sectional view of another'form of lighting fixture embodying my invention, and 4 Figure 4 is'afragmentary vertical'se'ctional view of a'thirdform'of lighting semen: v v i V 1 terminals 29 and 291n the compartment27 bodying my invention.

Referring specifically to the I drawing'and more particularly to Figures 1 and 2, my in vention in itspresent embodiment comprises a refiector designated generallyat R and com- .posed of an outer section'lO and an inner section 11 preferably constructed. of sheet metal of suitable gage. 'Thesection 10 is formed to provide' aninverted cup or dome-shaped por- 5'5; tion'12' from which depends and flares outwardly an annular 'portio'n or flange 13 of concavo convex cross-section, having its underside suitably treatedto provide'a .refleeting surface 14. The section 11 is in the form of a disk of concavo-conv'e x cross-see tion, the peripheral edge of which seats in an annular-groove 'lii formed'in the section 10 at the juncture between its portions 12 and 13. V 1 i The underside of the section ll is' suitably treated to provide a reflecting surface 16 forminga continuation of thereflecting surface-14 of the section l0, and the two sections are secured together by two bolts l'f'cxtendi0 ing through diametrically opposed openings in thed'ome shaped portion 12 and through slots 18 inthe section 11, the bolts being provided "withnuts 19 for clamping'the two sections t'ogether. o In the form shown in Figuresrl and 2', the bolts l7are otsufiicientlength' to receive exteriorly of the section 10, convention'al two part insulators- 20 which co-act to clamp thereto bymeans of other nuts 21 on the g bolts, feed wires2'2 and 23 from'which are tappedbraiich -ivires-24 and 25. insertable through -diainetrically opposed'slots 26 in the 'domeshaped portion 10, into 'a 'co'mpermeate? which the two reflector sections co actto form when they are-assembled'as shown in the'drawing. I V

Theslots 26 are formed by extruding the metal of the section 10 so as toprovide hoods I 28 which functionto prevent the ingress of i water through the slots into the compartme'nt27; The section 11 is'provided with a central opening inwhichis received and se cured, a conventional two part lamp socket 29 providinga socket section29 into which a lanip Lis screwed, as well as providing for the con'nectioifof the*branch "wires 24 and '25 theretolto supplycurrent to the lamp.

Thedonieshaped portion 12 of the sec- In installing the form of fixture above described, the supporting wire 34: is passed through the eye 33 of the bolt E, after which the previously strung feed wires 22 and 23 are clamped to the insulators 20 by the bolts 17 and the nuts 21 so that the feed wires will be supported from the fixture and be main tained in definite spaced relation. 7 The branch wires 2 1 and 25 are now con- J nected to the feed wires and can be clamped with the latter by the insulators as shown. The free ends ofthe branch wires are then passed through the slots 26 in the section 10, and it will be understood that the branch wires are of sufficient length to permit their easy connection to the terminals of the lamp socket 29 when applied to the section 11, and with the latter disassembled from the section 10 by removing the nuts 19. When the connection of the branch wires to the terminals of the sign receptacle has been-made, the section 11 is applied to the section 10 so that the free ends of the bolts 3A5). 17 extend through the slots 18 in the section 11, after which the nuts 19 are applied to the bolts, to thus secure the two reflector sections together, with the terminals of the sign receptacle and any excess length of the 4 0; branch wires enclosed in the weatherproof compartment 27. The lamp L can now be screwed into the socket of the receptacle 29;

so that with the feed wires included in circuit with a source of current supply, the fixu; ture will be ready for use. p

" It will be manifest fromthe foregoing de scription that the fixture will be suspended solely by the supporting wire 34, and that the feed wires22 and 23 will in turn be sup 5;), ported and maintained in spaced relation by the fixture, all in such manner as to permit the necessary connections ofthe feed wires to supply current to a lamp in the fixture, with the utmost ease and dispatch.

Referring now to Figure 3 I have herein shown another form of lighting fixture embodying my invention and particularly adapted for outdoor use with a supporting pipe carrying the feed wires 36 and 37 the insulators 20 as well as the slots 26 in the reflector section 10 are dispensed with; the

This iormof fixture is identical in construetion to the first form with the exception that of the section 10, and being threaded externally to receive nuts 39 for securing the section 10 to the pipe. The feed wires 36 and 37 are of sufficient length to permit of their connection to the receptacle 29 in the same manner as the feed wires 22 and 23 described in conjunction with the first form of my invention. t

Referring now to Figure 4., I have herein shown 'a third form of my invention particularly adapted for'indoor'use with a chain 40 for suspending the fixture, which is identical in-construction to the first form dewires 22 and 23 described in the first form of my invention.

It will be understood that as the insulators 20 aredispensedwith in the forms of my invention shownlin Figure .3 and 1, that the bolts 17 need only beof sufiicient length to pass through the sections. 10.and 11 and receive the nuts 19 for securing the two sections together, and it will be m'anifestthat in all forms of my invention,.the section 10 and the section 11. having the socket'29 are secured together in the same manner to form the compartment 27, and thus permit the connection of feed wires to the receptacle with the utmost ease and dispatch, all while enclosing the terminalsof the receptacle and any excess length of the wires in the compartment when the sections are assembled.

Although I have herein shown and described only three forms of lighting fixture embodying my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.
